SBEGIGATEQN forming part of Letters Patent No. 671,215, dated April 2, 1901.

Application tiled September '7, 1900. berial No. 29,278. (No model.)

To @ZZ whom t may concern/ Be it known that I, BLA KEMNYFY, a subject of the Emperor of Austria-Hungary, and a resident of Trk St. Miklos, in the Kingdom of Hungary, Empire of Austiia-llungary, have invented ce1-tain new and useful Iniprovements in Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to plows; and it is the special object of the same to produce a plow by means of which the plowing depth and breadth may be adjusted. The plowbeam is secured to the plow-body, carrying the colter and the share, by'means of a bolt, which is drawn down by a rod or chain lixed to`the steering device. The plowing depth is regulated by means of the set-screw located on top ot' and near the rear end of the plowbeam. When the whole system is lowered, then the set-screw pushes against the plowbody, and when raised by pushing down the handles it is secured in this position by a sliding frame, so that the colter and share may be carried free when the plow is not in actual operation. This plow is also -charactei-ized by the arrangement that the plowbeam is turnable on a bolt sliding in a frame fixed on the wheel-axles for the purpose of altering the plowing breadth.

The invention is illustrated in the accompanying drawings, in which- Figure l illustrates the'plow in side view. Fig. 2 is a plan View of same, and Fig. 3 represents in front View the regulating device.

The plow-beam is composed of two parts a b, which are joined to the plow-body c by means of a bolt CZ. The plow-body carries the colter c and the share f. The steering device consists of a plate h, engaging a frame which surrounds the bolt Zt, secured in a frame p q. A frame 'i is connected to the bolt Zr. by means of a rod or chain Z or by other suitable means. Through the front end of the leverarm of the plow-beam passes the bolt Zo and through its rear end b a set-screw m., which rests on a sliding frame fn., actuated by the rod o and located between the handles as long as the colter and share are carried above the ground. These parts are shown in this position in Fig. l. I

The plow Works as followsz. When the rod o and the frame 'n are withdrawn, then the set-screw 'm is disengaged, and when the horses start the chain Z works on the bolt (Z in such a manner to draw it down, together with the body c, the colter c, and the sharef, so that the latter enters into the ground. In doing so the set-screw pushes against the plow-body and limits the downward movement of the whole system. The plowing depth is therefore regulated by the set-screw fm. The whole system comes thus in a position indicated in dotted lines in Fig. l, and the bolt Zt is a little backward, so as to allow the plow-beam and the plow-body to move freely. When after work the plower desires to carry the plow free, he raises the body,with the colter and the share, by pressing down the handles and shoving the frame n under the set-screw m. The latter can be secured by any suitable device, such as a chain with padlock, andA is thus secured against an arbitrary displacing, so that the plower is not able to plow in any other than the desired and prescribed depth. The variations of the plowing breadth are eected by drawing the bolt k ont of the frame p 1 and taking out the Lipper frame-plateq in the pillars r 1', Fig. 3, and then engaging the bolt 7o in another hole in the lower frame-plate p. As the bolt 7c is connected to the plow-beam, the latter effects the lateral movements of the share. This plow has the advantage that the plower can only plow in this prescribed depth, which is regulated by the set-screw m, and, further, it is not necessary to raise the handles when the plow is to be carried free, so that it can never happen that the plower trails the share over streets on the way home, which would be very damaging, especially on good roads. During the work it is not necessary to press down the handles, because the share is drawn toward the ground by the steering device and the chain Z. The plow-carriage is completely unburdened and not pressed toward the ground, so that this plow requires but little traction-power.

IOO

Having thus described my invention, I claim and desire to secure by Letters Patentl. A plow com posed of a plow-beam ct b, a plow-body c joined thereto by a bolt d, a co1- ter e and share f carried by the plow-body, a rod or chain Z Xed to the steering device which draws down the plow-body, a set-screw provided with a locking device and situated on top of and near the rear end of the plowbeam; when the colter and share are lowered then the set-screw pushes against the plowbeam, limiting thus the entry of the share in the ground, substantially as described.

2. A plow composed of a plow-beam a b, a plow-body c joined thereto by a bolt d, a colter e and share fcarried by the plow-body, a

l rod or chainl fixed to the steering device which draws down the plow-body, a set-screw provided with a locking device and situated on top of and near the rear end of the plowbeam; when the colter and share are lowered then the set-screw pushes against the plowbeam, limiting thus the entry of the share in the ground; and a frame p q, a removable upper frame-plate q, pillars 7" r and plate provided With a bolt 7i; which latter passes through the front end of the plow-beam, the bolt ls movable vertically and laterally for the purpose of altering the plowing breadth, as specified.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribingr witnesses.

BLA KEMNYFY.
